Leviticus 15:25-30

25‘1Now if a woman has a discharge of her blood for many days, not at the period of her menstrual impurity, or if she has a discharge beyond 2that period, for all the days of her impure discharge she shall continue as though 3in her menstrual impurity; she is unclean. 26Any bed on which she lies all the days of her discharge shall be to her like 4her bed at menstruation; and every object on which she sits shall be unclean, like 5her uncleanness at that time. 27Likewise, whoever touches them shall be unclean, and shall wash his clothes and bathe in water and be unclean until evening. 28When she becomes clean from her discharge, she shall count off for herself seven days; and afterward she will be clean. 29Then on the eighth day she shall take for herself two turtledoves or two young doves, and bring them to the priest, to the doorway of the tent of meeting. 30And the priest shall offer the 6one as a 7sin offering, and the other as a burnt offering. So the priest shall make atonement on her behalf before the Lord because of her impure discharge.’
